spacefm: warnings on startup, missing dependencies, thumbnails don't work

[ryantm]

I installed spacefm on nixos-unstable channel. I observed a couple of problems:

1. Most of the program icons are missing.
2. Thumbnails do not work. I tried view -> preferences, click "show thumbnails" asked to edit /etc/spacefm and said it was going to ask for a root password. After that thumbnails still did not work but the checkbox shows checked.

Adding

    hicolor_icon_theme
    gnome3.adwaita-icon-theme

as dependencies, fixes the icon warnings. Leaving the only warning on startup as:

$ spacefm

** (.spacefm-wrapped:14409): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

** (.spacefm-wrapped:14409): WARNING **: No root settings found in /etc/spacefm/  Setting a root editor in Preferences should remove this warning on startup.   Otherwise commands run as root may present a security risk.

[ryantm]

Turning on the at-spi2-core service fixes the accessibility warning.

  services.gnome3.at-spi2-core.enable = true;

[ryantm]

This looks relevant to

** (.spacefm-wrapped:14409): WARNING **: No root settings found in /etc/spacefm/  Setting a root editor in Preferences should remove this warning on startup.   Otherwise commands run as root may present a security risk.

Is this issue fixed by #9681 ?

[ryantm]

@lethalman Unfortunately, no. I didn't figure out how to fix the thumbnailing.

[ryantm]

On my system, it is not coming up with the correct mime-type for a .jpg file, so that might be why the thumbnails are not working.

[pSub]

I haven't tried, but I guess the solution I have purposed for #9679 should also work here.

[vcunat]

The mime problem might be fixed by afdfe76.

[vcunat]

And the thumbnailing issue does seem same as in #9679. (I don't know a good solution though.)

[nioncode]

Are these issues still relevant? Also see my recent fix #36797, which should improve the mime-type situation.

[ryantm]

I'm not sure, I stopped using spacefm. I'll close this.

Thumbnails aren’t working for me at all, for anything. I have the “show thumbnails” option checked. I’m using SpaceFM 1.0.5 in Ubuntu MATE 18.04 LTS. (note: I originally posted this at #9679, whoops)
